The EU’s drugs regulator has approved the use of the Oxford-AstraZeneca Covid vaccine for all adults.
The European Medicines Agency (EMA) said the AstraZeneca vaccine was about 60% effective in the trials on which it based its decision.
The move comes amid a dispute over whether AstraZeneca is breaking its vaccine delivery commitments to the EU.
The European Commission has published its contract with the Anglo-Swedish drug-maker, hoping to show a breach.
The bloc agreed to buy up to 400 million doses of the AstraZeneca vaccine last year.
In a press conference later on Friday, Astra-Zeneca chief executive Pascal Soriot conceded that it had “teething issues” in the yield of vaccine at some production sites.
“We’re talking about biology manufacturing here,” he said, adding – “it’s not like doing an orange juice.”
Mr Soriot said AstraZeneca had millions of doses ready to ship to the EU, and was working 24/7 to increase capacity.
